Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Non-Insulin-Dependent Diabetes Mellitus

Intervention: rosiglitazone-metformin fixed dose combination (Drug); metformin + glimepiride (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: GlaxoSmithKline

Official(s) and/or principal investigator(s):
GSK Clinical Trials, MD, Study Director, Affiliation: GlaxoSmithKline

Summary

A better glycemic control is associated with less complications (cardiac diseases, blindness, etcetera) for type 2 diabetic patients. The objective is to study if rosiglitazone may lead to a more regular glycemic pattern with less hyperglycemia and hypoglycemia episodes than with a sulphonylurea (glimepiride).

Clinical Details

Official title: Comparison of the Effects of Rosiglitazone and Glimepiride, Both Given in Combination With Metformin, on 24-Hour Glycemia in Type 2 Diabetes Patients Not Controlled With Metformin Alone. A 3-Month Multicentre, Randomized, Parallel-Group, Open-Label Study.

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Duration of Hyperglycaemia (>126 mg/dL) in Hours at Baseline Compared to After 12 Weeks on Treatment

Episodes of Hyperglycaemia (>126 mg/dL) at Baseline Compared to After 12 Weeks on Treatment

Secondary outcome:

Duration of Severe Hyperglycaemia (>150 mg/dL) in Hours at Baseline Compared to After 12 Weeks on Treatment

Episodes of Severe Hyperglycaemia (>150 mg/dL) at Baseline Compared to After 12 Weeks on Treatment

Duration of Hypoglycaemia (<80 mg/dL) in Hours at Baseline Compared to After 12 Weeks on Treatment

Eligibility

Minimum age: 40 Years. Maximum age: 80 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Males and females aged 40 to 80 years

- Diagnosis of type 2 diabetes mellitus for at least 6 months

- Body mass index (BMI) ≥25kg/m2

- 7%≥HbA1c ≤ 9% at visit 2

- Treatment with metformin between 1. 7g/day and 3g/day for at least 12 weeks prior to

visit 1

- Female subjects must be non-pregnant, post-menopausal, surgically sterile or using

effective contraceptive measures

- Written informed consent

Exclusion Criteria:

- Use of any oral antidiabetic drug other than metformin within 12 weeks prior to

screening

- Significant hypersensitivity to thiazolidinediones and sulfonylureas or compounds

with similar chemical structure

- Subjects who have required the use of insulin for glycaemic control at any time in

the past or subject with a history of metabolic acidosis including diabetic ketoacidosis

- Subjects with clinically significant ongoing oedema or with a history of oedema in

the 12 months prior to visit 1

- Subjects with a history of severe hypoglycaemia

- Anemia defined by haemoglobin concentration <11. 0g/dL for males or <10. 0g/dL for

females

- Renal disease or renal dysfunction, e. g. as suggested by serum creatinine levels

≥135µmol/L in males and ≥110µmol/L in females

- Presence of clinically significant hepatic disease (i. e. ALT, AST, total bilirubin or

alkaline phosphatase >2. 5 times the upper limit of the normal reference range)

- Congestive heart failure (NYHA class I to IV), unstable or severe angina, recent

myocardial infarction

- Subjects with chronic diseases requiring periodic or intermittent treatment with oral

or intravenous corticosteroids

- Female who are lactating, pregnant, or planning to become pregnant

- Any clinically significant abnormality identified at screening which in the judgement

of the investigator makes the subject unsuitable for inclusion in the study (e. g. physical examination, laboratory test, ECG, ...)

- Use of any investigational agent within 30 days or 5 half-lives (whichever is longer)

prior to enrolment in this study

- Active alcohol, drug or medication abuse within the last 6 months or any condition

that would indicate the likelihood of poor subject compliance

- Subjects not willing to comply with the procedures described in this protocol.
